The Delta Works


The Maeslantkering (Maeslant barrier) is a storm surge barrier on the Nieuwe Waterweg. It was constructed from 1991 to 1997. As part of the Delta Works the barrier responds to water level predictions calculated by a centralized computer system called BOS. It automatically closes when Rotterdam is threatened by floods.

Maeslantkering has two 210 meters long barrier gates, with two 237 meters long steel trusses holding them. When closed, the barrier will protect the entire width (360 meters) of the Nieuwe Waterweg, the main waterway of Port of Rotterdam. It is one of the largest moving structures on Earth, rivalling the Green Bank Telescope in the United States and the Bagger 288 excavator in Germany.  (Wikipedia)

This is a poster of the actual Maaslantkering.  It's much too big to take a photo from ground level.


We took the car ferry from Maasluis to Rozenburg.

The Delta Works

The Delta Works is a series of construction projects in the southwest of the Netherlands to protect a large area of land around the Rhine-Meuse-Scheldt delta from the sea. Constructed between 1954 and 1997, the works consist of dams, sluices, locks, dykes, levees, and storm surge barriers. (Wikipedia)

Before the long drive home, we stopped in Zierikzee for lunch.
